' To all whom it may concern:

'Be it known that I, 'Gnoncn ll. Nam- LINGER, a citizen of the United Star/es, and a resident 'of East Grange, in the county 'of Essex and State of New Jersey, have invented a new and Improved "Closing-Guide for Collapsible Tubes, 'of which the followin is a full, clear, and exact description.

his invention relates to collapsible tubes and the manufacture of collapsible tubes. More particularly, the invention relates to means and methods for properly'closing the end of the tube.

A collapsible tube, as is well known, is a container used forthe distribution andsale of all manner of toiletarticles, such asshaving creams and the like preparations. The collapsible tube is capable of being rolled from one end to ej ct the contents from the other end. The tube as used in the market usually bears the name of the contents with directions for administering same, and with the manufacturers name printed on the tube for observance by purchasers and users.

In manufacturing collapsibletubes it isthe usual practice to employ a sheet-metal blank which is placed in a special machine with punching dies which bend up the metal blank to form a cylindrical tube. The tube is then printed to show the directions, contents, the name of the manufacturer, and other pertinent information. One end of the cylinder is usually closed with a screw-threaded cap, and the other end is closed by pinchin the collapsible tube together after being lled, after which the pinched end is folded over to form a hermetically-sealed joint. It is the pinching and folding operation of the open end to form a sealed joint with which my invention has to do and which particulary forms the basis of .the present disclo sure.

In the filling or collapsible tubes on t e with its sea ed end printed portions do not form a symmetrical and well-shaped container. When the closed and sealed end of "the tube does not come; within the same plane as the printing on the tube, the con tainer, when sitting on a shelf or displayed in a drugstore cabinet, will not have its printed portions facing directly the observer, but the jprinted directions, the name 'ofth'e contents and the manufacturers title, will be partly obscured by ex'tendingaround the cylindrical bodyof the tube and not directed inthe plane of vision.

It is fitting, therefore, that the primary purpose and object of my invention is to .provide means and manufacturing methods to facilitate the closing and sealing opera- .tionof thetc'ollapsible tube'to the end that the operators and mechanics employed in a collapsible-tube "filling factory will be guided and directed in applying the. closing machine to the tube so that the finally closed end will be in the same plane with the printed portions, or will be. alined with the printed portions of the collapsible tube in order that the tube will better display the printing "when supported in a vertical position, and will form afbetter made product and present a more shapely and symmetrical appearance than has heretofore been possible.

To this end I present the following invention, and display in picture form ways and means of effectually carrying out the aforesaid processes. A collapsible tube and clos- 111g machine constructed and used in accordancewith the plans of my invention employs a guide line printed on thebottom'portion of the tube to indicate the position where the closing machine must be applied in order to form a well-closed end even with and in the same plane with the printed portions of the tube. The crux of my invention, therefore, relates to means to indicate the relative position of the "closing machine with the printing on the collapsibletube in order that the closing machine may be applied parallel to the bottom end of the tube; and, furthermore, to cause the folded end to assume a folded position perpendicular to the axis of the tube.

In the followin description there is set forth a more detai ed analysis of my invention, and in the appended claims there are defined several modifications and forms of the invention. The accompanying drawings distrade-marks,advertising matter and descripl 40 use, and upon the closed end of the ;tube'be-.

ing pinched and rolled ,to eifect'a-Vdischarge ofthe contents, that'the readingmatter is:

sealed, and flattened outwith a view of more clearly illustrating the application of my mvention. i r v Fig. 2 is a perspective view of atube employing my improved construction, and

,prior to its application to a crimping machine, and I i Fig. 3 is a fragmentary perspective view of the upp'erend of the tube subsequent to its having been completed, and subjected to the. conventional crimping action. 7

Referring now more particularlyto Fig. 1, it will be seen that the illustration of this figure has been resorted to with a view of clearly indicating the position of the usual tions upon the body of the tube, 6. e. preferably at diametrically-opposite points in-the, I

best adapted to immediate recognition on face of the finished tube..

With a View of avoiding a coiiiiu'sion If have indicated this advertising matter, di-

rections, etc. by means ofpanels 7 and 8 appearing upon the body 6 of the tube itj being understood that the body of the same presents-in normal appearance, the shape shown in Fig. 2, inwhich this body is identified by the reference numeral 9.

As has been pointed out in the preamble, considerable difiiculty has been experienced incidentto'the' fact that the crimping machine, applied to the open end of the filled tube does not engage the same in planes'par- I I} said tube subsequent to the samebeingfilled. 2. As. an article of manufacture, a coljlapsible tube'having panelsof Written mat- ;ter upon its face, and means also appearing allel to the advertising Thus the iadvertising and directions are not'fr'eely presented;

to a customer, aside from the fact that in oftendestroyed toa point'at which thesame may not be read.

'With this in view,-I convenientlyprovide an indicatingmark of any suitable character, which might conveniently bev termed closing guide. I II the reference numeral 10, and it will be seen, I reference beingv had to'Figs'. 1 and 2, that the same is substantially in llne with one of the panels. Thus anindicating means is jpro-' vided for the operator of the crimping or This mark is identified by clamping machine, and upon the operator presenting the filled tube to the jaws of the semen a position at which the jaws will even'substantially- 'aline with the indicating mark 10, it will be appreciated that the free edges of the tube will be closed in the manner indicated in Fig. 3, 2'. e. that the advertising matter and directions will appear at diametrically opposite points in the face of the tube 9, and not in line with the line of bending, to which the body of the tube will be subjected while in use.

i From the foregoing it will be appreciated that I have rovided meansacting as a closingguide which will serve to permit theoperator of a clamping or crimping machine to properly associate the tube with the same,

to lnsure a proper closing of the free end ofthe tubewhereby the panels 7'and 8.will

befreely presented to the view of the cusitomer, and may subsequently, be examined even upon charged.

Obviously any form of indicating mark the tube having its contents dis- Having thus described my 1 1. As an article of manufacture, a collapsible tube having panels of written; matter appearing upon its face, and means also appearing upon the outer face of said tube,
